Turning Emissions into Assets: Converting Bromine Plant Carbon Dioxide to Magnesium Carbonate for Sustainable Growth and Emission Reduction

Aarjav Jain, M.R Gandhi

Abstract: This study examines the feasibility of reusing carbon dioxide (CO2) emitted from bromine plants to produce magnesium, with a focus on its potential for reducing greenhouse gas emissions and promoting sustainable practices. The research involves capturing and purifying CO2from bromine plants and converting it into magnesium carbonate through chemical reactions. The objective is to assess the viability of this approach and its environmental and economic implications. The study finds that capturing and purifying CO2 emissions from bromine plants is achievable through various techniques such as adsorption, pre-combustion capture, and direct capture from waste streams. Purification methods like pressure swing adsorption and selective absorption are employed to remove impurities, ensuring the quality and suitability of the CO2 stream for further utilization. The conversion of CO2 into magnesium carbonate is successfully accomplished through mineral carbonation and solvent-based absorption processes. These methods demonstrate high absorption efficiency, with solvent-based absorption achieving an efficiency of 85% and the mineral carbonation process reaching an absorption rate of 78%. The yield of magnesium carbonate is also substantial, with the solvent-based absorption process achieving 92% and the mineral carbonation process achieving 85% of the theoretical maximum.
